I-485 Adjustment of Status

[Marymary01]

Hello everyone, I have a pending case with the USCIS since October 2017. Recently, I got a call from an Officer who introduced himself by name (Withheld) and demanded to speak with my husband (Petitioner) as he has questions for him.
After discussing the incident with our attorney mentioned the officer’s name, he told us that he’s a marriage fraud unit investigative officer with the USCIS and we have to be up and ready per our case.....I have never heard of that prior to now that a case would be labeled as fraud without an interview.
Has anyone been in a situation like what I described? My husband and I want to know what to expect and prepare for at this point.
Thank you

What kind of evidence did you submit with your 485 application? If it is not adequate this raises suspicion. See what additional evidence you can provide
